Perhaps this is the right moment for a little bit of feedback:Additional ISO values: I exclusively shot RAW, thus, this feature is not useful to me.Spot metering: a great feature, could not be happier with my camera now.Factory menu: just interesting.Focus frame pattern: I mostly use the central focus point, and just occasionally one of the others; I personally do not like having more than one focus point active.Extended Av compensation: as long as the meter on the viewfinder can only display +/-2EV, I cannot figure out how to benefit from this feature.Extended FLASH compensation: a great feature; with a fast lens and the flash set to -4EV to -6EV, I have just rediscovered the integrated flash.Extended AEB: I use three shots at 2EV when hand-holding the camera, and many more at 1EV when using a tripod. Having a wider separation is not that useful to me; now, having more than three shots would be great.Safety shift: another great feature.Shutter count: just interesting.ISO in viewfinder: very interesting, but perhaps needs a bit of polishing to become perfect.Color temperature: I shot RAW and do the white balance during post-processing, but this sounds great.Flash / AF assist beam: This can be set somewhere else, so I do not find them very interesting. And, speaking of such duplicated settings, mirror lock-up is way too hidden in the menus, and I use it quite frequently; having a faster access to that setting would be great.RAW at AUTO: I never shot AUTO.AUTO-ISO: I personally do not find this interesting at all.As I said in a previous post: thank you very much for your efforts.
AutoISO function uses shuter speed value which was displayed on lcd in Tv or M modes, not saved value, to set min. shuter speed.
I didn't find where to get measured light value from light meter to calculate ISO.

Before I had this, I used to manually adjust the screen brightness when I used a -EV setting, so I could see approximately what I was getting. This reduces two steps - one of them buried down in the menu system and not calibrated - to one. On my new G12, with its dedicated dial for Ev compensation and its Live View screen, I can interactively tweak the brightness of my images, which I found useful this fall in taking foliage shots. This might be an area to explore for the 400D hack, though it wouldn't be live view. At this point, we can use the small ISO increments the same way, though coupling the playback screen brightness to the Ev dial as well as to the ISO expansion would be more intuitive for brightness-tweaking.- I agree about the value of spot metering - which I'll use when I have a severely backlit subject.- I like the current implementation of the focus frame system, though I'm not sure how often I'll actually use it. It seems most useful to those shooting sports - I'm mainly a landscape shooter.- Though I've been a photographer for half a century, I'm an available-light shooter. I've only used flash once in taking a picture, and that was as a "fill light" for a severely backlit subject. I'm actually unclear on what flash compensation does. If it allows you to throttle back the amount of flash to make its effect more subtle, that looks useful for taking event candids, not something I do very often.- AEB looks interesting for High Dynamic Range use, if varies the shutter speed or ISO while leaving the aperture alone. I've gotten HDR effects by taking advantage of the wider dynamic range of a single RAW file in the first place, importing it at different brightness or exposure settings into different layers and merging the results.- Safety shift - if it works by tweaking the ISO - looks like an "only when absolutely needed" AutoISO and as such valuable for dealing with unexpected changes.- I try to set the right color temperature when shooting - I figure this keeps adjustments during post-processing within the useful range.- RAW at AUTO seems useful if I have to hand the camera to a friend or family member who doesn't really know how to use it.- AutoISO seems dangerous, so I'm happy simply enabling Safety Shift, if it works by tweaking the ISO when absolutely necessary. I am also very grateful for the work Sergei has done to make my XTi feel new again.
Dangerous when we can't limit the max ISO. Automatic between 100 and 400 ISO will be a good start.
"Enabling Safety Shift, if it works by tweaking the ISO when absolutely necessary" is a very good solution. By lack of light, diaphragm and shutter speed stabilize on screen and facilitates the AutoISO calculation ?

Hello everyone.First I would like to thank Sergei for his excellent firmware and the constant effort then I would like to report a small bug found on the latest version of firmware released (autoexec_2010-12-13a),I think that has not been previously reported :When the 400d is in M or TV mode AND the flash is open and active, if I use the right/left arrows to change the iso the camera automatically sets the value of time on "bulb".I hope I was clear, and I apologize for my very rusty English.From Italy,Riccardo.edit:In Tv mode, the camera sets " 30'' ", not "bulb".
